Simon takes a loan from Ayanda to the value of R25 000 to start up a new business. Ayanda charges him interest at 12% per annum compounded semi-annually. Three years after he took out the loan, Simon repays an amount of R12 000. Ayanda then changes the loan agreement and charges Simon interest at the rate of 15% per annum compounded monthly for a further 2 years. At the end of the first year of this new agreement, Simon borrows a further R10 000. Draw a time-line for the loan as described above. Calculate the amount of money that Simon owes after 5 years.
